...and I can think of alot of servers that will BL those customers. DUL
blacklists are very commonly used. However "legitimate" these MS Exchange
servers are, they'd better get a static IP if they want to avoid problems

My guess is that since many of the BL's are being DDoS'd. perhaps AOL came
up with their own, possibly out of date DUL-type BL...
